Citrix Certification Path

Citrix Certification

There are four separate certifications offered by Citrix:

1) Citrix Certified Sales Professional (CCSP)
2) Citrix Certified Administrator (CCA)
3) Citrix Certified Enterprise Administrator (CCEA)
4) Citrix Certified Instructor (CCI)

Let's look at each of these separately.


Citrix Certified Sales Professional

Like the name implies, The Citrix Certified Sales
Professional (CCSP) certification is intended for those who
sell Citrix products. By taking the corresponding course
and passing a Web-based exam, Citrix certifies you as being
knowledgeable enough about their products to sell them (but
not actually run them). Yuck.


Citrix Certified Administrator

Now we're getting to the good stuff. By passing one of four
exams (you get to pick which one), you can become a Citrix
Certified Administrator (CCA). Here are the exams you can
choose from:

1. Exam 118, Citrix WinFrame 1.8 Administrator


2. Exam 212, Citrix MetaFrame 1.8 Administrator


3. Exam 220, Citrix MetaFrame XP Administrator 1.0 for Windows


4. Exam 310, Citrix MetaFrame 1.0 or 1.1 Administrator for UNIX
   operating systems

The CCA is very entry level - pass one exam and you're
certified. It is roughly equivalent to Microsoft's MCP and
Cisco's CCNA certifications.


Citrix Certified Enterprise Administrator

If you've already attained your CCA and work with Citrix
products on a daily basis, then achieving Citrix Certified
Enterprise Administrator (CCEA) status is the next logical
step. You are required to pass four additional exams to
attain your CCEA.

You must pass the following two exams:

1. Exam 910, Citrix Resource Management Services


2. Exam 950, Citrix Nfuse Administration

Then, you need to pass one of these two exams:

1. Exam 911, Citrix Resource Manager


2. Exam 921, Citrix Installation Manager

Finally, you must also pass one of these three exams:

1. Exam 920, Citrix Installation Management Services


2. Exam 930, Secure ICA and Security


3. Exam 940, Load Balancing Services

After you've passed the necessary exams, submit proof of
your CCA and your exam scores to Citrix. Your status will
be upgraded then to a CCEA.


Citrix Certified Instructor

If you want to deliver Citrix instruction at a Citrix
Authorized Learning Center (CALC), then you must be a
Citrix Certified Instructor. The requirements to become a
CCI aren't terribly stringent. Here are the required steps:

1. Hold a current certification for Windows NT/2000 or UNIX
   - depending on what you plan to instruct on.


2. Sit the CCA Course you intend to instruct and pass the
   corresponding exam with a score greater than 80 percent
   (this gives you CCA status).


3. Attend a very expensive Citrix-approved "Train the Trainer"
   course (those who currently hold a CTT, MCT, CNI or
   equivalent certification are exempt from this step).


4. Submit proof of the above to Citrix, and you will receive
   a certificate and your CCI number as well as CCI benefits.

What is OS/2

OS/2 is a computer operating system, initially created by Microsoft and IBM, then later developed by IBM exclusively. The name stands for "Operating System/2," because it was introduced as part of the same generation change release as IBM's "Personal System/2 (PS/2)" line of second-generation personal computers. OS/2 is no longer marketed by IBM, and IBM standard support for OS/2 was discontinued on 31 December 2006.[1] Currently, Serenity Systems sells OS/2 under the brand name eComStation.

OS/2 was intended as a protected mode successor of PC-DOS. Notably, basic system calls were modeled after MS-DOS calls; their names even started with "Dos" and it was possible to create "Family Mode" applications: text mode applications that could work on both systems.[2] Because of this heritage, OS/2 shares similarities with Unix, Xenix, and Windows in many ways.

About XenApp

Citrix XenApp (formerly Citrix MetaFrame Server and Citrix Presentation Server) is an application virtualization/application delivery product that allows users to connect to their corporate applications. XenApp can either host applications on central servers and allow users to interact with them remotely or stream and deliver them to user devices for local execution.

XenApp began life as an application hosting solution. Only since 2007 has XenApp included application virtualization and streaming technologies that enable application delivery to user devices. The core XenApp application hosting technology utilizes Citrix Systems' proprietary presentation layer protocol or thin client protocol called Independent Computing Architecture (ICA). The Microsoft Remote Desktop Protocol, part of Microsoft's Terminal Services, is based on Citrix technology and was licensed from Citrix in 1997. [2]

Unlike framebuffered protocols like VNC, ICA transmits high-level window display information, much like the X11 protocol, as opposed to purely graphical information. The Citrix Display Driver is installed in Session Space and captures high level GDI draw commands, which can be replayed on GDI-capable clients, for example Windows-based clients. Clients are available for several operating systems, including Microsoft Windows (CE, 16-bit, 32-bit and 64-bit platforms), Mac OS, Linux, and other Unix-like systems.

Citrix MetaFrame version 3.x and 4.x servers listen for client connections on TCP port 2598, by default. [3][4] If the Session Reliability feature is disabled, then the server will listen on port 1494. Older MetaFrame servers (those running MetaFrame version 2.x or earlier) do not have the Session Reliability feature, and therefore always default to port 1494.

Both local and hosted application delivery methods in XenApp leverage existing network transmission protocols including TCP, HTTP, HTTPS, SMB and CIFS.

The Citrix Developer Network contains a set of software development kits that enable custom development for XenApp. These SDKs include the following:

* Citrix XenApp SDK
* Citrix Virtual Channel SDK
* Citrix ICA Client Object SDK
* Citrix Web Interface SDK
* Citrix Simulation API SDK

XenApp components, including application hosting servers, if any, reside on a Microsoft Windows computer, which can be either standalone or part of a larger cluster (farm) of Citrix servers. It is important to note that in addition to concurrent user Citrix licensing, there must exist a Terminal Server Client Access License (CAL) and a Windows Server CAL from Microsoft for each client connection. Both products must be adequately licensed for the environment to function correctly.

There is a web-based Citrix client, freely available under the name Web Interface for XenApp. The Web Interface may be used as a secure ICA proxy over HTTPS when combined with Citrix Secure Gateway, both of which are included in the base XenApp product. XenApp also supports three UNIX variants: HP-UX, Solaris, and AIX which are included in Enterprise and Platinum editions of XenApp.
[edit] UNIX version

Presentation Server for UNIX is available for Solaris (SPARC and x86), AIX, and HP-UX. Patches typically come out first for the Solaris version. The product started as MetaFrame for Solaris 1.0 which was released in March 2000.[5] MetaFrame for UNIX (MFU) 1.1 added support for AIX and HP-UX and came out in the fall of that year and Feature Release 1 came out about a year later. The next version came out in the first half of 2003. It was originally planned as MFU 1.1 Feature Release 2 but was rebranded MetaFrame Presentation Server for UNIX 1.2.[6] However, references to MFU 1.1. FR2 can still be found (e.g. in the license key). Presentation Server for UNIX (PSU) 4.0 was released in the first half of 2005 and was the first version to be bundled with the Presentation Server suite.[7] Existing customers paying for upgrades and new versions (known as Subscription Advantage) can however continue to get just the UNIX version. Existing MFU 1.x installs cannot be upgraded to PSU4; instead a clean install is required.

History Of Citrix

Citrix was founded in 1989 by former IBM developer Ed Iacobucci in Richardson, Texas with $3 million in funding. Iacobucci quickly moved the company to Coral Springs, Florida since he lived there when he had worked at IBM. [2]

Citrix was originally named Citrus but changed its name after an existing company claimed trademark rights. The Citrix name is a portmanteau of Citrus and UNIX.

Many of the original founding members had participated in the IBM OS/2 project. Iacobucci's vision was to build OS/2 with multi-user support. IBM was not interested in this idea so Iacobucci left. Iacobucci was offered a job at Microsoft as chief technical officer of its networking group but turned it down to start his own company.[2]

The company's first product was Citrix MULTIUSER, which was based on OS/2. Citrix licensed the OS/2 source code from Microsoft, bypassing IBM. Citrix hoped to capture part of the UNIX market by making it easy to deploy text-based OS/2 applications. The product failed to find a market. This was due in part to Microsoft declaring in 1991 that they were not going to support OS/2 anymore.[2]

Roger Roberts was appointed the CEO of Citrix in 1990. Roberts, a Texan, came from Texas Instruments.

From 1989 to 1995, the company did not turn a profit. In 1989 and 1990 there was no income at all.

Between 1991 and 1993, Citrix received funding from both Intel and Microsoft as well as venture capitalists. Without the help of this funding, Citrix would not have survived.[2]

In 1993, Citrix introduced WinView, which provided remote access to DOS and Windows 3.1 applications on a multi-user platform. It became Citrix's first successful product. In 1995, WinFrame, based on Windows NT 3.5, was released. WinFrame was sanctioned by Microsoft and embraced by the enterprise businesses. WinFrame pushed Citrix into having widespread adoption.

As part of these successes, the company went public in December 1995.[2]
[edit] Microsoft relationship

Citrix obtained a source code license to Microsoft's Windows NT 3.51. In 1995, they shipped a multiuser version of Windows NT with remote access, known as WinFrame. This product gained widespread acceptance, and enabled the company to become more profitable.

During the development of WinFrame for Windows NT 4, Microsoft decided that it did not want to license Windows NT 4 source code to Citrix. Not only that, Microsoft threatened to build its own version.[2][3] Citrix and Microsoft entered negotiations about how best to solve this dilemma.[2][3] After negotiations, Microsoft agreed to license Citrix technology for Windows NT Server 4.0, resulting in Windows Terminal Server Edition[4][5]. Citrix agreed not to ship a competing product but retained the right to sell an extension to Microsoft's products, initially under the name MetaFrame. This relationship continued into the Windows 2000 Server and Windows Server 2003 eras, with Citrix offering Metaframe XP and Presentation Server. On February 11, 2008, Citrix changed the name of its Presentation Server product line to XenApp.
